Problems solved by technology

However, the ring-shaped bottom plate of this structure is a rigid flat plate, which cannot closely fit complex terrain
At the same time, its structure is fixed, and it cannot respond in real time with the development of the scour pit shape
In the process of gradual development of erosion, its protective effect will be greatly reduced

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1-8 As shown, a foldable terrain adaptive pier scour protection device includes a bracket 2 arranged outside the pier; the bracket 2 includes a first bracket 21 arranged outside the pier 1 and can slide along it, and the outside of the first bracket 21 is provided with n A rod-shaped second bracket 23 with the same structure and rotatable along it, n≥2; a flexible anti-shock pad 4 is arranged between adjacent second brackets 23; Weight bag3.

[0028] The first counterweight pockets 3 are arc-shaped and distributed along the directions of m rings with different radii concentric with the pier 1 .

[0029] A second weight bag 8 is arranged under the second bracket 23 . A through hole 7 is provided on the anti-scourr cushion layer 4 , and the first confinement ring 51 passes through the through-hole to connect the anti-sco...

Abstract

The invention discloses a foldable terrain self-adaptive pier scouring protection device. The device comprises a support arranged on the outer side of a pier; the support comprises a first support which is arranged outside the pier and can slide along the pier; n rod-shaped second supports which are the same in structure and can rotate along the first support are arranged on the outer side of thefirst support, wherein n is larger than or equal to 2. The device further comprises flexible anti-scour cushion layers arranged between every two adjacent second supports. The device also comprises first counterweight bags connected with the anti-scour cushion layers. The device is simple in structure, convenient to install, low in cost and high in practicability; the position of the anti-scour cushion layers can be adjusted in real time in all stages of scour development, the anti-scour cushion layers are attached to a riverbed, manual intervention is not needed, and automatic operation is achieved.

Description

technical field [0001] The invention relates to a bridge pier protection device, in particular to a foldable topography self-adaptive bridge pier scour protection device. Background technique [0002] Scouring is one of the most important factors causing bridge diseases, and it is the process of water digging away from the substructure of the bridge and carrying away sediment and other substances. Scouring can occur at any time, and it is particularly strong during floods, which can easily lead to structural damage and instability of bridges. Damage during floods is often unpredictable, and this uncertainty makes addressing scour more difficult. Yi Renyan collected 106 bridge collapse accidents in China during the operation period from 2000 to 2014, 30% of which were caused by erosion. The direct economic loss caused by floods in flood seasons every year is as many as several billion yuan, and it shows an increasing trend year by year. [0003] At present, bridge scour pr...
